I'm really interested in how it shoots. I also would like to know how it is on copper fouling and what if any velocity/pressure problems you may encounter. The treatment is certianly radical to use on a stainless poly barrel so we will all be watching it closely. Since many have standard 18" BHW barrels for a comparison this will be intersting. Get some baseline numbers with something like Winchester White Box 55 grainers.
PS: Congratulations on a very sharp looking barrel.
The best firearm for self defense? Any loaded one will do.
I would imagine that the surface area has been increased by a tremendous amount, and cooling should be increased, but what about rigidity? I don't see it weakening it, since the design is a strong shape.
